If it takes four years to teach a basically proficient student to program at the BA level (which we've seen it does), why would anyone expect to be able to teach a true beginner to the same level in the same time? Perhaps there could be a special program in which a student spent 1 year intensively studying programming between high school and college. That might be able to bring motivated students into readiness.
